Build Log

Graham VR1A + Krick Borkum


Well I have switched my next steam build from a Billings African Queen conversion to using a Krick Borkum kit.
I could not see only using part of the Billings kit and converting it to steam.
This will be an easier build and I like the look of the Borkum hull better.
It is a little longer and a lot wider so my boiler will not look out of scale.
I will be using the same steam setup.
A Graham VR1A single cylinder engine with a home made boiler and Bix gas burner system.
I am adding a steam shutoff valve and water level tube to the boiler now.
I may change the inside mounting set up in the boat so the boiler is more in the center of the hull as I don't like the boiler up in the bow.
It just looks funny to me.
That will depend on how much of a PITA it would be.
Here are some basic photos of the hull and steam plant.
I will post some photos of the boiler mods soon. Dave.

Thanks.
I was going to try and run without a water gage but the more I thought about it the more I did not like the idea.
In my Saito I always know if I add the required amounts of water and fuel the fuel will always run out first.
But I am not sure how long the gas burner will run and I don't want a meltdown.
I will be doing some time trials to get an idea of the run time after the boiler is back together. Dave.

Here is a photo of the shut off valve and water gage I added to my boiler.
The pressure test looks good. Now to steam it up and see if everything is still working. Dave.

I can't believe it has been a year since I started this thread.
Things keep coming up and delaying the start but Mr Peconic has shamed me into getting the ball rolling with his excellent build using the VR1A.
I will dust off my plans today and pull out the kit.
This has been long enough. Dave.

Thanks guys!
Well today I took all the parts out of the HUGE box and proceeded to cut out all the nice laser cut wood parts.
What did not look like a lot of parts quickly turned into a SHIPLOAD of parts.
I am glad I just stocked up on glue.
BTW-The kit came with a nice 60MM (2.36") four bladed brass prop.
I hope it is not to big for the VR1A.
I do like to see a nice slow engine speed in my steam boats.
It looks and sounds more realistic. Dave.

I wanted to show a little progress and the interesting engine coupler supplied with the kit.
The photo basically shows it all.
There is a plastic tube that goes over the screw that the contact arm rides on.
I think it may actually allow the engine to reverse easier.
Giving about 1/2 rotation with no prop load. Time will tell. Dave.

Your boiler really looks good Dave.
Will you modify the looks of the hull much?

Thanks Reg.
It is the first boiler I have ever made.
It is a low pressure boiler. The safety valve is set for 12PSI if I remember right. Although I have CRS big time.
I will build the kit stock.
At first I was going to modify the inside so the boiler sat in the center of the hull but it would have been some major changes so I nixed that idea.
I really like the look of the hull. It is super wide. Dave.

BTW-Here are a few more Borkum photos I found on the net.
Sorry I don't know who the builders are. Dave.

I installed the main internal framework today which is the hardest part of the entire build.
You need ten hands to get it all epoxied up and installed before things set up.
I decided to do it in steps. The first being the areas I cannot get to with more epoxy.
Then add a filet to the inside and let it cure upside down.
Check out my balancing act with the weight. Dave.
