Re: 24 volt electric heat problem

I would be very suspicious of the current requirements of a forklift motor. Does the motor have four wires? If yes, you are wasting power with a field winding. You need to use a permanent magnet motor ( two wires). Are there any ID plates that tell the motor specs? After determining the current draw...

Re: Conversion factors

As already stated, converting feet is easy feet times 1.5 or 1.6" Make up your own table for the inches, there are only 11 of them. 1" divided by 12" equals .0833. Take that time your scale. .0833 X 1.5 =.125" for 1 scale inch. This can be further divided by 4 or 8 for scale 1/8's and 1/4's". Busy w...

Re: Newbie has truck bolster questions

Do not forget to check coupler height with a normal nominal load ( the engineer and some water)!

Re: clishay

I happen to have the orginal article scanned and on file. It is about 106,000 kb. Fits nicely on a disk. Willing to mail it to England. I am not sure how you can securely provide your address to me.

Re: Miniature Barrel Bolts

If they will be more decorative then operational, you could try Evergreen brand extruded plastic sheet, square tubes and rods from your local hobby shop.

Re: Train Mountain News

Just received emails that Vertels revoked the agreement between Timberlake and Train Mountain effective the 12th unless TM show that TM is still viable. IE, closing the leased tracks.

Re: 4QD controller for interurban

How many wires on one of the motors? 2 wires is a permanent magnet style. It should attract your steel tools. Four wire could be either of the other two types.
Study the heavy battery wires. How they wired to the batteries should help figure what voltage is being used.

Re: Sweet William steam locomotive discussion

A couple 0-4-0's, the 'Elda' and the 'Lyndam' where construction articles in 'Live Steam. They are tank types with tenders for the engineer. A Porter, the 'Marie Estelle' was also in 'Live Steam as a series.
Reference material!

Re: Trailer Features

The old rule I remember, is that tongue weight should equal 10% of the gross weight to prevent swaying (fishtailing). I pulled a boat and trailer that was over 7000lb with about 535lb on the tongue. Tracked like on rails! Just very hard on the standard tongue that came with the trailer-broke, only r...

Re: scale and narrow gauge

US standard gauge is 4' 8 1/2" or 4.708 ft In the popular scales, rail gauge would equal 3/4" = 3.531" 1"= 4.708" 1 1/2"=7.062" and 1.6"=7.533" for standard guage equipment. Actual model track guages are close numbers of convience. Standard prototype equipment dimensions are scaled down with the run...

Re: Crown Sheet Height

All those little 3/8 tube will equal about 1.7 sq inches of area. The 7/8" tubes equal about .5 sq inch area each. Four more of them would be a whole lots of less work to install. For reference the Railroad Supply Heavy Mike has a 12" boiler with 26 1" tubes. That is 1/2 the inside diameter squared ...
