Hi Gang: I've tested the voltage drop over 10 screw connections. Used a 15 amp heater as a load at 120 volts. After 10 minutes the light extension cord I used was getting warm, but not the PVC terminals. My digital meters showed a 0.1 volt drop over the ten connections. I also used an analog ( needle ) volt meter and I could barely see the needle move. So I would say the connections are better than a cheap extension cord. Please remember, I'm only suggesting these PVC terminal strips for use at less than 20 volts. Best wishes, Carl.
Hello Mike:Can you give us some part numbers? I looked at DigiKey and they had 67K items for wiring. Thanks, Carl.
You are right, that could be a problem. You could cut the PVC to leave ridges between the screws. Or put counterbores at each screw location. But many model railroad have bare connections everywhere under the tables. I've even seen 120 volts connections "protected" by a "Don't Touch!" label. For a bit more safety you could put the terninals in a case or cover them with clear plastic. Thank you, Carl.
Nice terminals. But you need to strip the wires and there is less room to write on them. Safer too with recessed screws. Both have their advantages and minuses.Carl.
Hello John: There is some damage when you remove a screw. I don't use a screw on the same spot twice, just move over a bit. The wire can be quite chewed up, so nip off the bad spot. I haven't had to replace a terminal board yet, but what the heck, it wouldn't cost much to replace anyway. Good luck, Carl.
Hello Algr1: These terminal blocks are ONLY for low voltage ( below 12 volt ). I used a 120 volt heater only as a test to see the reaction to high current. I plan to do a second test to see the voltage drop at the connection. I'll report the results here. The intended use of these connections are for model train layouts where the power is only on when you are in the room. It would be interesting to see if a very high current could burn the connections loose. Thank you for your concern. Carl.
Hello Charles:By wiring the battery case I can still use the standard batteries if they have a charge.Carl.
Hello MJ: I found the long common trough made for a messy group of connecting wires. I like the serpentine much better since the wires lay to the top or bottom of the strip. I also found if I cut grooves in both directions it weaken the PVC too much and the "blocks" would break loose. Do you mean Homosote? I like the PVC since it doesn't hold or collect moisture that could lead to minor "shorts" or other odd signals. Thanks, Carl.

Hello Gadisha: My runner up idea was a house boat / bardge. I thought I could park my VW Bug on the back to run a paddle wheel. Then I realized I could only tour rivers and would need to stay at marinas. Beebe and Clegg wrote about their private railroad car, The Virginia City". It cost them $240 a day to travel on the railroads, back in 1959! Best wishes, Carl.
Hi Tool Man:Back in 1979 PEX wasn't available, only metal and PVC. Polybutylene from Qest was the new kid on the block. I had two fitting failures, both my fault. I put fittings directly into the water heater tank, just where the instructions said not to.Thanks, Carl.
Hello SpiderMax:When I lived in the Bus it was always clean and had fresh paint on the outside. Over 30 years in the yard with little maintenance took its toll. There is still an empty spot in the back yard and my heart where it last rested.Thanks, Carl.

Hello W: I was afraid the nails would wiggle loose on the road. I really like screws and only use them where a bolt, washer and nut won't fit. Plus I really like the feel of a well driven screw. Thanks for looking. Carl.
Hello Carlos: Yes, marine grade plywood would be better. I used the 6mm plywood because we keep our camper in a garage so it should never stay wet again. Also I had the 6mm plywood. I didn't mention that I found half the Bamboo flooring on the side of the road and only needed to buy one bundle to finish? Thanks for reading! Carl.

I like to wrap power cords in a figure "8" pattern. It keeps the internal wire from wrapping up and tearing the outer insulation. The coat hooks are very nice. I've used tarp hooks also.
Wind power cords with a figure "8" pattern. That way it doesn't twist up the internal wires. Long extension cords are often ruined this way to the point the outer insulation tears up. Carl.
Very Nice Job!
Hi Gang: I've been making anti-freeze drawers for years:https://www.instructables.com/id/Jug-Shelves/The smaller oil jugs are nice addition. Thank you for sharing.
If you use two or three screws the wooden stalk will not twist. Carl.
Way Cool! I really like the tire marks. Thank you for sharing. Carl.

A-Liner Pop-up Campers use stress panels too. Thinner plywood inside (4mm) and aluminum or fiberglass outside. I still have the cut out if you need some. Carl.
Hi Gang:I drill steel at about 1000 RPM for a 1/4" bit. Then if I drill a larger hole go slower, 1/2" is twice as large so go half as fast, 500 RPM. And the smaller holes is just the opposie, spin an 1/8" bit 2000 RPM. And you only need to get close, most step pulleys change speed in steps of hundreds of RPM anyway, no need to use PI to six digits.Good Luck! Carl.

Hello: If I needed a lot of HDPE sheet do you have any idea what the total cost is? I think it would be mostly your time to clean, melt and mold plus running the oven at perhaps 20¢ an hour. McMaster-Carr has HDPE sheets for about 25¢ a cubic inch. Thanks, Carl.https://www.mcmaster.com/#hdpe-sheets/=19x8k37

Hi Gang:I started doing this in 1974 with the cardboard from baloney packages. I find the paint can lids more permanent. ( and less smelly )Carl.
Very nice job. The press fit to the motor shaft is common. In older toy trains the stress of the press fit can lead to splitting, so don't skimp on the diameter of the hub. I've added brass rings to fix split hubs with good results. Good luck and thank you for the inspiration.

Hello RuthS1:Take the centimeters and divide by 2.54 will equal inches.Take the millimeters and divide by 25.4 will equal inches.The strips are about 6" wide and the slots are 2" deep. The width of the slots will need to be adjusted to the OSB thickness and if you paint the boards first.Also you may be buying OSB in the USA and it will be 48" x 96", so you will need to work out new dimensions anyway. I've been making shelves like this for years. See:https://www.instructables.com/id/Jug-Shelves/Good luck, Carl.
Hello Blanchae: Quite the opposite, at the shop I worked they bought a hydraulic press to have more control of the ( slow ) speed. With the crank presses they could change the motor pulley, but that only helped a little. On progressive draw dies they might have 5 draw steps before the part reached the finial shape. Press work can be neat! Carl.
Hello: As a former Die Maker I would like to suggest changing the shape of your blank. Also we would have a pressure plate hold the edge of the blank to avoid wrinkles around the edge. We also would have punched the center hole after drawing the shape. Lubrication is a must. Impressive work! Carl.
Hello Again: Cool Shape, did I mention I had worked at Speidel? Carl.

We did this with our Cat Cindy, but the bell was outside. If Cindy wanted to stay out all night we would pull the bell inside so she wouldn't wake us.It was funny when Mother would excuse herself from the phone saying: "The Cat is ringing the door bell, I need to let her in,"Thanks, Carl.

Hi Gang:Just re-read the post about multiple swing doors like they display poster on. What If you did it in a corner of your shop. The hinge points would be on a diagonal across the corner. Then all the doors could swing 90 ° both ways before hitting.Carl.
Nice job, Thanks. Carl.
Wow! I never figured on using the pegboard for any accuracy. My work is fairly rough, but it looks better if all the parts are "wrong" by the same amount! If the angle must be right I use guide boards and C-clamps. Thanks for looking!

Hi Gang:For my tent I cut a blue tarp to size for a ground cloth. I put grommets and innertube rubber band to latch them to the corner stakes. The advantage is it is just the right size and doesn't stick out to gather water from the roof.Then I cut a second tarp over sized for the inside. I have had an inch of water in the tent and my sleeping bag was still dry in this tarp boat.Thanks, Carl.
Hi Gang: I made six of these for around the house. If I make more I will skip the glue and use a short cross wire to hold the sock down. ( The Palmetto Bug Stomp is our local dance weekend )Thanks, Carl.
I think that is a great idea. I do have similar cards with threaded holes that are store bought. Once you get all the 1/4" bolts in one spot it is easy to see the fine and course threads. Thanks!
