Shave horse

I just finished panelling my new shop area that will be used for chairmaking. I will be starting construction on a shave horse for this area. What I have in mind is the adjustable english style shave horse designed by Brian Boggs. I would like it if anyone who uses a shavehorse or has used one to let me know if there is anything I should know before I start. Is this style a good choice for the various operations involved in Windsor chair making? I have heard the dumbhead style horse makes it easier for certain operations,but only briefly. I have never used a shavehorse so I know almost nothing. Just what little I have read.Any comments are welcome. Thanks---Jack
