I can’t see how that would work, trying to back pedal to stop. Or do you stop and remove the chain from one cog, move the wheel in the drops and put the chain on the other cog? Here is the chainring I’m using. I’m going to grind off the sewage on a steel cottered exercise bike crank and weld on...

Trying to measure hub to hub distance with two very different hub flange diameters. There is probably a better way, like taking my small metal ruler and sliding it across. The measurement this way would still be off because of the angle. A right angle with two small rulers held at the right...

So this idea works.

Suicide shifter

Calculations for spoke length of the rear hub. Non drive side of the hub flange. Drive side hub diameter measurement.

Got a photo?)

I’m going to try to see if I can get a derailleur to work. It’s a Stumy Archer Three speed internally geared drum brake hub. I removed both cog spacers and put on a dished 23 tooth 3/32 cog, teeth inward, on first, then a 16 tooth 3/32 dished cog teeth outward. Since it’s not a coaster brake a...

I was lucky, my jury rigged measurements were right. The wheel is spoked.., but not trued. My truing stand and spoke wrenches are at our house and we’re not living there now. I used a slotted screwdriver to get the nipples snug, but not tight. Drives me nuts that it takes so long to do something...

I can’t make edits on this site. I made a mistake. It’s 7 holes counterclockwise when placing the second side key spoke on a rim drilled with the first spoke down to the right of the valve stem hole,

I used an old cable with a lead head, lead head in a nipple, nipple with lead head in a rim hole, stretched across to the opposite hole, inserted another nipple, made a mark with a permanent marker on the cable at the nipple top and stretched the cable across a piece of cardboard, put marks from...

Ross 1983 Force One. I’m the second owner.Fifteen speed, pretty high grunty gearing.

Covid project. I stick welded, wire welded and brazed up a Breezer 1 tribute.

This is a good idea but it will probably be flawed in the execution. The real old SA drum brake units had a thread on cog. You could thread on a three speed cassette.

No, I went home to start my truck and ATV. I picked this stuff up to keep me busy.

Today I messed around with my SA model AW drum brake 3 speed hub. I took out both spacers, used two 3/32 dished cogs, put the big cog dish facing the spokes and the small dished cog facing away from the spokes. I used 16x23 teeth. The snap ring fits perfectly. I have welded a steel mounting...

I ordered spokes but I messed up. I forgot to change the delivery address to my in-laws. The spokes will be delivered to our home, 108 miles round trip away. Dang, who knows when I’ll get there? I need to get out there to start my truck, ATV and snowblower.

I’ve made no progress. December 1 I had a mini stroke, couldn’t talk. In the hospital for 3 days. Then I caught hospital acquired bacterial pneumonia and was back in the hospital for 11 days. I’m now living with relatives for a few months as I recover. No tools or parts here. I might see if I...

I’m really nursing mine along. The charging port is worn out so if it charges it seems to depend on something mysterious, like the moon phase. It’s been like this for over a year.

Yesterday I ordered a new iPad. I’m thinking this will help. It won’t be here for 11 days as they are on sale but out of stock. Then it will take me forever to get it up and figured out. The strange thing is my problems are only on RRB.

You need a big hardwood fire, a leaf blower or shop vac exhaust as an oxygen source. I wrapped the pre fluxed brazing rods around the joints and added a lot of powdered brazing flux. The cooled flux is like glass and the only thing that took it off was the pink foam grit wheels on my angle...
